LASTI NG-MACHINE.

SPECIFICATION forming part of Letters Patent No. 251,205, dated December20, 18 81.

Application filed September 24, 1879.

To all whom "Lt may concern Be it known that I, WM. E. FISCHER, ofBoston, county of Suffolk, State of Massachusetts, have invented anImprovement in Lasting-Machines, of which the following description, inconnection with the accompanying drawings, is a specification.

This invention relates to lasting-machines for lasting boots and shoes.

In the machine herein described the last is mounted on a support whichis so sustained as to exert an upward pressure upon the last, the normalcondition of the last-support being such as to elevate the bottom of thelast above the line of action of the heel and toe lasting devices, thelevel of the last-bottom being determined by a stop. The side-lastingdevices, herein shown as plates adapted to operate against the upperalong the sides of the last and lay the edges of the upper over on theface of the inner sole, and also the india-rubber rubbing-piecesattached to the said side-lasting devices, are as in other earliermachines. The heel and toe lasting devices are composed of independentradially-moving fingers, each be- 'ing so supported as to beindependently actuated or moved horizontally over the heel and toe endsof the last or inner sole. The sidelasting devices having laid the sideedges of the upper over upon the inner sole, the central finger of eachset of heel and toe lasting devices is then moved to crowd the upper atthe extremity of the heel and toe over upon the inner sole, they actingto sweep the wrinkles at said extremities laterally with relation to aline drawn along the center of the lasts bottom from heel to toe,throwing all the wrinkles about the curved parts of the said toe andheel into the space between the said central fingers and the side-lasting devices nearest them, after which the finger-plates are automaticallythrown forward, acting upon the wrinkled and full portions of the upperbetween the central fingers and side-lastin g devices and crowding thesaid portions over upon the face of the inner sole. The finger-plates,moving radially into the space between the central fingers andside-lastin g devices, prevent the upper being folded or caught betweenthe edges of the central fingers and finger-plates each side of them.Just within the toe-lasting fingers,

and having its acting portion within the are occupied by the front endsof the toe-lasting fingers when drawn back, is a toe-piece supported ona spring, it being adapted to come against the upper at the toe of thelast when thelatter, with the upper andinner sole thereon,

and the toe-lasting devices are being changed vertically as to theirpositions with relation to each other, the inner sole being then actedupon more or less near the ends of the last by the downholds. The saiddownholds are shown as adj ustably connected with an arm, so that,resting in contact with the inner sole at two points between its toe andheel, they will position the heel and toe with relation to each otherand prevent the "last tipping longitudinally as the relative verticalposition of the side-lasting devices and last-bottom are automaticallychanged with relation to each other, in order that the side-lastin gdevices, when subsequently automatically moved forward during thefurther movement of the actuating parts of the machine, shall correctlymeet, act upon, and lay the edges of the upper over upon the face of theinner sole. The toe-restan independent device located just back of thetoepie'ce-is shown as a concaved or curved metal plate supported by aspring, the latter spring enabling the toe-rest to yield as the relativepositions of the last-bottom and side-lasting devices are changedvertically, while the metal plate is also adapted, by reason of itsflexibility, to permit a slight-roll of the last laterally, to

enable the side-lasting and toe and heel lastthe edges of the last.

Figure 1 represents, in side elevation, a lasting-machine containing myinvention; Fig. 2, a vertical section thereof on the line 00 :10, thebottom of the last and inner sole thereon being above the level of theline of action of the side-lasting devices, and the hold-downs orpressers being in position to come in contact with the inner sole at twopoints between its ends; Fig. 3, a top view of the machine after theside and heel and toe lasting devices have been closed over upon theinner sole and the hold-downs have been automatically released and movedaway from the inner sole. Figs. 4

and 5 are details in two different positions of the lower end of thelever or arm upon which the hold-downs or pressers are mounted, and theactuating devices therefor; Fig. 6, a detail in longitudinal section ofthe toe-lasting devices, their adjustable carriage, and toe-rest; Fig.7, a top view of the toe-lasting devices, the central finger only havingbeen moved forward; and Fig. 8 is a top view of the elbow-lever oractuating device for acting upon the arms which carry the toe and heellasting fingers or fingerplates.

The frame a of the machine is and will be of suitable shape to hold themoving parts.

The side-lasting jaws or devices b (shown as plates) are connected byscrews with the removable pieces or blocks 0, the latter being attachedto the vibrating arms or side-lastingjaw carriers 01 by screws 0, thesaid blocks being also provided with elastic rubbing-pieces], such asdescribed in my patent of the United States No. 44,916. These arms d arepivoted onarod,g, are connected bya retracting-spring, h, and areprovided at their lower ends with rollers i, adapted to be acted upon bya suitable wedge,j, or other device, to at the proper time cause thejaws to approach each other and the last to act upon the edges of theupper along 1 the sides of the last and force said side edges of theupper over upon the face of the innerv sole, to be there secured bysuitable nails, tacks, or pegs.

The jaws may be changed for shoes of different length.

The last is mounted upon a support, 1, (shown as apinjointed toarod,m,in turn pivoted at 2 upon apivoted lever, 72, having adjustablyattached to it a weight, 0, the whole constituting a jack orheel-support,) which acts to press upward the bottom of the last andinner sole to a level above the line of action of the side lastin gdevices when operating to lay the upper over upon the inner sole.

The position attained by the inner sole above the side-lasting devicesis controlled by the stop 19, against which the lever nstrikes in itsdescent.

The toe and heel lasting devices are each composed of three fingers orplates-viz., central fingers, r, and two radially-moving fingerplates, 8or s. The central fingers, having inclined side edges, as shown in Fig.3, to act upon the upper at the extreme toe and heel and sweep thewrinkles laterally from the extremities of the said toe and heel as theends of the central fingers move the upper over upon the face of theinner sole, are connected with the upper ends of spring-arms t, which intheir normal condition operate to retract the said central fingers; andthe finger-plates, adapted to be moved radially over the inner sole nearthe corners of the toe of the shoe, or at the outer inclined edges ofthe central fingers, to act upon the most wrinkled part of the edge ofthe upper, or that part of the said edge of the upper between the closedside-lasting devices and the sides of the central fingers, r, are car--ried at the upper ends of spring or yielding arms a, which when in theirnormal condition operate to retract the finger-plates. These arms t andu are carried upon horizontally-act justable heel and toe carriages w w,fitted in suitable guideways in frame at. These arms t u are acted uponto close the central fingers, r, and then the finger-plates s or s bymeans of a cam-plate, a, (see Figs. 6 and 8,) forming partof anelbow-lever, 3, mounted on a rod in an ear, 4, .of the carriage, andprovided with rollers 5, to be acted upon by a suitable wedge or device,6, on a rod, 7, provided with an adjustable shoulder, 8, and a pin, 9,to be acted upon alternately by the treadle or main actuatinglever 10,when it is desired to close the heel and toe jaws upon the upper, thesaid wedge 6 acting with its opposite inclined sides upon a roller, 14,of an arm, 15, pivoted to the toecarriage w.

The heel-carriage has an elbow-1ever,13,substantially like the one 3,except as'to the roller 5, and the said lever 13 is connected with thearm 15 by means of connecting devices, shown as rods 12, the said rodsbeingextended through the pin 16 in the elbow-lever 13, and beingconnectedat their outer ends with a cross-head, 17, having an adjustingdevice, 18, shown herein as ascrew, to thereby so position the levers 3and 13 that they will permit the spring-arms of the toe and heel lastingfingers to retract the same more or less to accommodate shoes ofdifferent length and curvature, the same adjusting device also affordingopportunity for adjustment of the heel and toe carriages w mlongitudinally.

The cam-plate a (see Fig. 8) has its edge so shaped that its part 19first acts upon the arm t and moves the central finger, r, forward itsfull distance, or substantially so, after which the edges act upon thearms a and move the finger-plates s or s forward radially, as beforedescribed, it being remembered that these finger-plates are not movedforward until after the side-lasting devices and the central fingers ofthe heel and toe lasting devices have been moved forward.

It will be noticed (see Fig. 7) that the inclined edges of the centralfinger (it having been moved forward from its dotted to its full lineposition, in which latter position it will lie over upon the toe oftheshoe or inner sole) and the edges of the finger-plates s or s aresubstantially in contact before the said fingerplates are moved forward,and consequently the latter, in their forward movement, shove thefullness or crimped and wrinkled parts of the edge of the upper overupon the inner sole, wiping the said wrinkles toward the edge of theupper and preventing the upper from being caught or pinched between thecentral fingers .and finger-plates; and it is also obvious that theuppercannot be caught between the fingerplates and ends of theside-lasting devices.

IIO

The toe-piece 21, having a curved and yieldiug face, is connected withthe upper endof a spring, 22, attached to the toe-rest, the saidtoe-piece standing in its normal position in advance of the edges of thecentral fingers and fin ger-plates when most retracted, so that theupper on the last, when the same is being crowded below the level of thetoe-lasting devices, will be acted upon about the toe of the last.

jnstably connected with the bar 28 by means The toe-rest is composed ofa flexible plate, 23, mounted upon a stem, 24, fitted in a socket madein the toe-carriage, the lower end of the stem being sustained upon aspring, 25, herein supposed to be of india-rubber, so as to permit therest to yield and descend snfficiently to enable the side-lastingdevices to operate properly upon the upper at the edges of the innersole, as hereinbefore described.

The pressers or downholds 26 27 are adof the screws or nuts 29 in slots30. This bar 28 forms part of an arm, 31, having an elongated slot, 32,fitted to a roller, 33, on one of the rods 9. The short end 34 of thisarm has an incline, 35, and a toe, 36.

A rod, 37, connected with the rod 9 is extended through one side of theslotted part of arm 31, as in Fig. 4, and outside of the said arm thesaid rod is provided with a spiral spring, 38. The lever 10, held up bythe spring 39, has connected with it the wedge-barj to close the jaws,and this wedge-bar, at its upper end, has pivoted to it, at 40, awedge-link, 41, provided with a cam-surface, 42. A roller, 43, iscarried by that one of the shafts g opposite the one about which the arm31 moves. The shoe upper and inner sole being upon the last and the lastbeing supported in the machine, as in Fig. 2, the arm 31 is turned fromits position in Fig. 3 to the position in Fig. 2, thedownholds orpressers coming in contact with and resting upon the face ofthe innersole at two points between the ends ot'theinner sole. In thispositionthe inclined end 35 of the arm 31, which is free to move,rests againstthe roller 43, as in Fig. 2. Now, ifthe treadle 10 isdepressed, thewedgebar J, as it descends, draws upon the link 41, while its notch 44engages the roller 45, held in the arm 31, and while the rear side ofthe link bears against the roller 43, as in Fig. 2,

and consequently the arm 31 is so moved by crowding the inner sole andlast-bottom down automatically to the proper level in a rightline, thisbeinginsured by reason oftheinclination of the opening 32 and-the Wedge35 which acts upon the roller 43. The pressers remain at rest and holdthe last pressed down so long as the straight face of the cam 42 actsupon the roller 45 and the incline 35 rests on roller 43. While-thehold-downs are so held stationary the wedgesj act upon the rollers 'i ofthe arms d and close the side-lastingjaws or devices to turn the upperover upon the inner sole, and as the lever 10 reaches the stop 8 thewedge 6 is drawn down to operate the levers 3 and 13 and close thecentral fingers of the heel and toe lasting devices over upon the heeland toe of the inner sole, after which the further descent of the lever10 causes the wedge 6 to further move the levers 3 and 13 and cams M, tocause the portions 20 to act upon the arms u of the fingerplates 8 or sand close them radially over upon the face of the inner sole, and whenthe side and toe lasting devices are all shut in, as in Fig. 3, thecam-surface 42 passes beyond and from between the rollers 43 45,permitting the spring 38 to throw the lower end of the arm 31 into thepositionshown in Fig. 5, which will cause the upper end of the arm 31and the pressers or hold-downs to be autoi-natically thrown laterallyaway from above and in contact with the inner sole and shoe,leavingtheupper laid over upon the inner sole and held by thejaws and fingers,free to be nailed or otherwise secured.

The finger-plates s are shown as folded, as at s so that they may yieldvertically to a small extent, as is desirable for some classes of Workand uppers. The shank-pin b adj ustably connected with the arm a actsupon the inner sole at the shank of the shoe and keeps it down closeupon the last, thereby facilitating tight lasting of the shoe at theshank.

I claim- 1. In a lasting-machine, lastingjaws or devices to press theedges of the upper over upon the inner sole, and twoindependently-adjustable pressers or downholds to bear upon the fore andrear part of the inner sole on the last, mechanismto operate the saidparts in their .proper order, whereby therelative vertical positions ofthe bottom of the last with the inner sole thereon and the lasting jawsor devices may be changed to enable the bottom of thelast, with theinnersole applied thereto at a level above the line of action of thesidelastingjaws or devices, to be placed at or just below the line ofaction of the said lasting devices, and mechanism to automatically lockand hold the last depressed while the edges of the upper are laid overupon the inner sole.

2. In a lasting-machine, a jointed last-support located at the heel endof the last, and mechanism to press it upward, and a rear-part downholdwhereby the heel end of the inner sole and last are forced closely incontact preparatory to lasting the boot or shoe, combined with anindependent vertically-movable toerest and a downhold to bear upon theinner sole at the fore part of the last, substantially as described.

3. In a lasting-machine, independent vertically-movable heel and toesupports, side-lastsole thereon at the proper level for the action ofthe side-lasting devices to crowd the edges of the upper over upon theinner sole.

4. In a lasting-machine, a support for the last, side-lasting devices,substantially as desoribed, and elastic shank rubbers to rub upon thesides of the upper on the last, combined with fore and rear partdownholds or pressers made vertically movable with relation to the lineof action of the side-lasting devices, substantially as described.

5. In an organized lasting-machine, independent verticallyanovable heeland toe supports for thelast, fore and rear part downholds, side-lastingdevices, and heel and toe lasting devices, each composed ofradiallymovable fingers, to operate upon the upper at the heel and toeends of the last, and mechanism to actuate the side-lasting devices toclose the upper at its sides over upon the last, and separate cams tosubsequently operate the radially-moving toe and heel lasting fingers tolast the toe and heel of the shoe, substantially as described.

6. The arm 31 for the downholds, slotted and supported as set forth,combined with opcrating devices, substantially as described,

and a spring adapted to move downward the said arm and release it at theproper time, substantially as described.

7. A last-support and toe and heel downholds or pressers, combined withmechanismto move them verti aly and to automatically release the saiddownholds after the operation of the lasting devices, substantially asdescribed.

8. In a lasting-machine, the adjustable-independent fore and rear partdownholds and the toepiece mounted upon a spring arm, combined withtoe-lasting plates and the toe-rest, to operate substantially asdescribed.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.
